This base-mounted end suction pump is constructed with a cast iron casing and utilizes a bronze impeller. It incorporates a stainless steel shaft paired with a bronze shaft sleeve, designed with a dry shaft configuration that prevents circulating fluid from contacting the shaft. The assembly accommodates a ceramic and EPT mechanical seal. This pump sustains an operating pressure of 125 PSI and utilizes center-line discharge for air venting. The bearing housing contains sealed-for-life ball bearings, and the internal components are engineered to allow service without disturbing system piping.
Powered by a 20 HP premium efficiency TEFC motor, this assembly operates at 3450 RPM, utilizes Aegis grounding, and accepts a 380-460V 3PH power supply, achieving a DOE PEI rating of 0.46. The 'S' in the SFI series denotes Taco's advanced Self-Sensing technology, which eliminates remote sensors and field wiring by using internal mathematical algorithms to calculate system resistance and automate variable flow. The included VFD is configured with a fused disconnect without bypass and holds an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
